Dylan Quick, 20, used an X-Acto knife and a scalpel in a rampage Tuesday that hurt 14 people. He has been charged with three counts of aggravated assault. Quick is scheduled to appear again in court Thursday.

A 20-year-old student has admitted a fantasy to kill led him to use an X-Acto knife and scalpel in a mass stabbing at a Lone Star College campus Tuesday.

Harris County Sheriff Adrian Garcia on Wednesday said Dylan Andrew Quick told investigators he had been fantasizing about stabbing people since he was 8 years old and that he had been planning the attack for awhile.

A judge on Wednesday ordered that Quick be held without bail. He will also have to undergo psychiatric tests.

At a jailhouse arraignment before dawn Wednesday, Harris County prosecutor Caroline Dozier told a magistrate that Quick had fantasies about stabbing people.

"In a videotaped confession, he admitted he stabbed the complainants with an X-Acto knife and a scalpel because of his fantasy to kill people," Dozier told the judge.

Garcia said investigators described Quick, who is hearing-impaired, as matter of fact and said he understood the questions and was forthcoming about relaying information about the attack.

Garcia said investigators did not know why he chose Wednesday for his attack or if anything specific instigated it. He said the victims seemed to have been chosen randomly.

Quick is charged with three counts of aggravated assault after the attacks that left 14 people injured about 11 a.m. on the college's Cy-Fair campus at 9191 Barker Cypress, according to the Harris County Sheriff's Office.

Of the 12 victims that were taken to hospitals after the attack, 10 have been released from the hospital and the two remaining are in good condition, according to a statement from Memorial Hermann Hospital.

Campus reopens

The campus reopened Wednesday morning for normal operations after officials canceled classes and other activities following the attacks.

In a matter of minutes, Quick allegedly slashed the victims near the Health Sciences building, spanning the first and second floors of the campus building. Students then chased him outside the building and helped subdue him before police arrived and arrested him.

Garcia said video surveillance of the incident aided in their investigation.

A campus alert was issued at 11:30 a.m. because officials believed there was a second attacker.

Quick was ordered to be evaluated by mental health officials. He is scheduled to appear in court Thursday. Court records Wednesday did not show any attorney for Quick.

Levy said there were no signs that Quick was a problem student. He had worked in the campus library and many there had kind things to say about him. They were shocked by what he is accused of doing, she said.

Garcia said the sheriff's office received an email from a concerned citizen describing an attack similar to Wednesday's in an Internet chat room. He said the sheriff's office is investigating whether there is a connection to Quick.

Jan. 22 shooting

It is the second time in recent months violence has erupted on a Lone Star College campus.

On Jan. 22, three people were wounded in a shooting at the college's North Harris campus in the 2700 block of W.W. Thorne. Deputies later identified the gunman as Trey Foster, who was then arrested and charged in the incident. The gunfire broke out after an altercation between Foster and another man.

Lone Star College's Cy-Fair campus serves about 19,000 students. It is one of six campuses that make up the college, which touts itself as the fast-growing community college system in the nation.
